1'0 It w/wm, it may concern:

Be it known that i, Anion: Ivl'ronnutv, a -itizcn oi the Renubhe oi France, and a resident oi 105 Boulevard Preire, Paris, in the 5 said Republic, engineer, have invented a new and useful Air-(,oinpressor Combined with an icxplosive-Motor, of which the following a specification.

The object of this invention is to provide a I This invention contemplates the use of a piston in a compressor which 1s I'GClpTOCZLtGd by air fed ii'oin'the motor, the said piston be-' ing utilized for driving the single-acting pistons of two air compressor cylinders for the purpose of supercompression of the air.

in theaccompanying drawings, Figure 1 is a section of a compressor constructed according to the present invention, Fig. 2 is an end view of the same, and Figs. '3 is :1. diagrammatic view showing the compressor connected to a four cylinder motor.

The compressor comprises a large piston to which reciprocates in the main cylinder 1).

his piston (L drives the two single-acting compressor pistons d d of smaller diameter through the interposition. of strong springs c c which serve to absorh'tlie shock at the ends of the strokes of the main piston; These single-acting compressor istons d d reciprocatein the oon'ipressor cy inders e c.

The compressor astluisconstructed is doubleacting and operates ei'l'ectively on both strokes. The compressor is connected to two of the motor explosion cylinders (or to several pairs of cylinders) by two tubes ff leading to the opposite sides of the main p1stion Pipes i open communication between the compressor cylii'ulers e c and the.

tuhesfj'" which lead to the'opposite sides oi the main piston.

Suction valves g g" are arranged to open and close cdininunication through'the pipes i i. ilhitlettubes y, la lead from the comprest s e e to a singie outlet Z, which outlet may he connected to shy suitable reservoir not shown herein. Exhaust valves h It open and close communication through the outlet tubes j, k. In the tubes which supply gas to the motor cylinders used for the supercompression, two-way cocks m m are located for closing the. supply of gas and opening the supply of air to these cylinders so that these cylinders may either draw in gas when they are desired to work normally or to draw in air where they are to be used in connection with the operation of the compressor. The cylinders of the motor which are not utilized for compressing air may he used for the normal working of the motor.

Cocks n n are located in the tubes ff between the cylinders 0 0 of themotor and the compressor so to be able to assistv the operation of the apparatus.

The operation of the apparatus is as follows. The suction cocks m m are turned so as to cut off the supply of gas to the motor cylinders 0 0 and permit the admission of air thereto. The out-out cocks n n are then opened. l/Vhen. the cylinder'o arrives at its compression stroke, the main piston. (1, is

moved from left to right and the compressor piston (1 will draw in through the suction valve 9 the air already compressed in said cylinder. The cylinder 0 when it arrives at its compression stroke, will in its turn move the main piston c from right to left and thus draw into the cylinder 6 the air previously.

compressed in the cylinder 0. T he piston (U will at the same time expel the air from the cylinder 6 into the tube lu through the valve h. The system' of pistons will therefore have imparted to them a re'cipn c'atingv movement synchronous with the travel of" the motor and because of the speed of the motor a practically continuous currentol air will be ejected through the outlet I. When Ith e main piston c is returning, the air ih ro versed into the cylinder oi the motor and the said cylinder being open to exhaust. allows the air to escape.

This apparatus is more especially advantageous in connection. with automobiles where it may be. used for producing the desired pressure for the rapidiniiation of mieninatic tires. It may, however, be used for driving by means of compressed air; any form of apparatus as, for example; apparatus mounted on auton'iobiles.

it will be seen that an apparatus conted hcrcinahovo set forth will be very iuiiuii compact.

What I claim 1st 1. The cc-mbination with an explosive motor, of a COHIPI'GSSOI' comprising a main. cylinder, a piston therein arranged to be reciprocated by air fed from the motor, two comprcssor cylinders, single-acting, pistons therein driven by the first named piston, pipes for opening communication from the opposite sides of the main cylinder to the compressor cylinders, suction valves in said pipes, outlet tubes for the compressor cylinders and exhaust valves for said outlet tubes.

2. The combination with an explosive motor, of a compressor comprising a cylinder, a piston therein, tubes opening communication between the motor and cylinder for the passage of air alternately to the opposite sides of the piston, two compressor cylinders, pistons therein driven by the first named piston, pipes opening connuunication between the compressor cylinders and the tubes leading from the motor, suction valves for said pipes, outlet tubes for thecompressor cylinders and exhaust valves for said outlet tubes.

3. The. combination with'an explosive motor, of a compressor comprising a cylinder, a

piston therein, tubes opening commul'lication between the motor and cylinder for the passage ol'alr alternately to the ()})]')(.).\It(, sldes of the piston, cocks in said tubes, two compressor cylinders, pistons therein drivcnby the first named piston, pipes opening communication between the compressor cylinders and the tubes leading, from the motor,

suction valves for said pipes, outlet tubes for the compressor cylinders and exhaust valves for said outlet tubes.

4. The combination With a multi-cylinder explosive motor, tubes for supplying gas to the motor cylinders and cocks for cutting off the gas supply and supplying air to certain of the motor cylinders, oi a cmnpressor co nprisinp a cylinder, :1 piston therein, tubes opening communication between the motor and cylinder for the passage of air alternately to the opposite sides of the piston, two compressor cylinders, pistons therein driven. by the first named piston, pipes opening coinn'lunication between the tubes leading from the motor to t he compressor cylinders, suction valves for the said pipes, outlet titles for the compressor cylinders antlexhsmst valves for said outlet tubes.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this tlnrd day of December, 1906.
